Question

If 5(3x-5) = 20, then
what is 6x -8?

Answer 1

10

Explanation:

5(3x-5) = 20 Distribute 5

15x-25 = 20 Add 25 to both sides

15x = 45 Divide both sides by 15 to find x

x = 3

Now substitute this value for x in the expression

6x -8 Substitute x for 3

6(3) -8 Multiply 6 and 3

18 -8 Subtract 8

10

I hope this helped! :)

Answer 2

If 5(3x-5) = 20 then you distribute the 5 leaving you with 15x - 25 = 20. Adding the 20 leaves you with 15x = 45. X=3.

To answer your question, 6(3)-8 is 16.
